I would use the search option for this forum to see what you can find, and also start your own thread. By starting your own thread you will be subscribed to it, and it will also make easier for you to track it If you should have a need.

Seams like the search function on here doesn't like me lol. Always says no results found for some of my most basic questions. I guess I'll start a thread, thanks for the help

Caring for a chrome-lined barrel: Are these barrels cleaned by simply using solvents and cloth? I'm assuming that you wouldn't run a copper brush through it, is that correct? (I realize that this is probably an extremely ignorant question, but I'd rather now than assume).

I use copper a few passes, and finish up with cloth. Last pass, a lightly oiled cloth to lightly coat the bore.

I just made a precision build, so I need to research barrel care for it. But copper won't scratch chrome. Chrome is will scratch copper, as its harder. Also chrome lining is more for a service/duty type application so I'm not babying it.

My 416 SS barrel is another story.

Need a definitive answer on this. I hear all the old Colt SP1's are chambered in 5.56 even if they're marked .223 Rem on the lower receiver. Does anyone know if this is true for sure? Mine was made in '71.
